COLOR-BINDING- PREI PARATION.

No Drawing.

The invention relates to color binding preparations and more especiallyto such color binding preparations that are adapted to be easily andreadily mixed with any dry 5 metal or earth color.

The object of the invention is to provide a color binding preparationwhich will be, when prepared according to the directions describedhereinafter, Weatherproof, waterproof, washable, and sanitary. I

Another object of the invention is to provide a colorbinding preparationadapted for use on inside and outside work, and giving a flat, velvetysurface.

A further object of the invention is to provide a color bindingpreparation, which is adapted to be used as a varnish.

A still further object of the invention is to provide a color bindingpreparation,

which is absolutely durable on fresh airdry concrete and on oldconcrete.

Another object of the invention is to provide a color bindingpreparation having an excellent elasticity making the preparationespecially adapted for painting sheet zinc.

Another object of the invention is to provide a color bindingpreparation, which is adapted to be used for painting paper, Wood,plaster, brick, stone, concrete, composition board, glass, tin, andiron.

A further object of the invention is to provide a color bindingpreparation adapted for painting churches, theatres, hotels, hospitals,sanitariums, schools, and other public build- Another object of theinvention is to provide a color binding preparation adapted to be usedfor painting plaster walls, and ceilings, and for imitatmg wall papers.

4 A still further object of the invention is to provide a color bindingpreparation, which will keep its beauty and brightness for years, iflightproof colors are being used in combination with said preparation.

Anotherobject of the invention is to provide a color bindingpreparation, which can be washed with soap and water.

Another object of the invention is to provide a color bindingpreparation, which is easier to mix and apply than the cold water andoil paints known and used heretofore.-

Another object of the invention is to pro- A pplication filed August 4,1926. SerIaI No. 127,185.

vide a color binding preparation adapted to be used in combination withchalk, thereby eliminating the use of the expensive and poisonous whitelead and zinc. Another object of the invention is to provide a colorbinding preparation adapted to be used for preparing disinfectant andgerm killing varnishes.

The new color binding preparation consists of the following ingredients:

Casein, glue, flour, linseed oil, china wood oil, borax, ammonia,thymol, benzol, and cobalt dryer.

Preferably said ingredients are'mixed in the following proportions:Casein 5.3 units, glue 0.3, flour 0.3, linseed oil 2.4, china wood oil3.7, borax 0.8, ammonia 0.1, thymol 0.03, benzol 0.1, and cobalt dryer0.01.

The 0.8 units borax may be replaced by 0.8 units of soda, or, ifdesired, 0.5 units of borax and 0.3 units of soda'may be used.

The cobalt dryer may be replaced by any other suitable mineral dryer.

The above mixture can still be improved by adding 0.04 units of phenoland 0.3 units of water.

This preparation produced as described above and is highly concentratedand should therefore be dissolved in accordance with the followingdirections: q

The preparation should be stirred thoroughly until all the oil will beWell mixed'with the other ingredients. An amount of water 5 equal to theamount of the preparation is then added, the water having a temperatureof approximately 160 degrees Fahrenheit. After mixing the Water and thepreparation thoroughly another amount of Water equal to the first amountand of the same temperature is added and the Whole is stirred until avthick paste is formed. 1

Then four more parts of Water of the same temperature are added,providing the preparation is to be used for outside work. In case ofinside work 'five more parts of Water may be added. The mixture must bestirred until a smooth creamy emulsion is obtained. This emulsion mustbe absolutely free from 100 lumps. It must b'e'kept in a clean dry andtightly closed can, until it is to be used. It may then be mixed withany desired dry metal or, earth color.

What I claim as new and desire to secure by letters patent is:

A color binder consisting in a mixture of the following ingredientscasein, glue, flour,

5 linseed oil, china wood oil, borax, ammonia,

thymol, benzol, and cobalt dryer in the following proportions: 5.3 unitsof casein, 0.3 units of glue, 0.3 units of flour, 2.4 units of linseedoil, 3.7 units of chinawood oil, 0.8.

units of borax, 0.1 unit of ammonia, 0.03 units of thymol, 0.1 unit ofbenzol, and 0.01 unit of cobalt dryer. I

In Witness whereof I have aflixed hereunto my signature.
